A Sun Tube is an innovative and effective means of transmitting natural daylight to otherwise poorly lit areas and with the ventilation options available the units can assist compliance with Building Regulations.

The skylights can be installed into new or existing roofs with ease and can be accommodated within most roof construction types.

Suitable for pitched and flat roofs specifying the required flashing kit above.

Sun Tubes can be purchased with a flexible or rigid tube and come complete with the neccessary flashing kits. The characteristics for both are as follows:

Rigid Tube System


Offers 98% reflection on inner surface. Up to 20 times more light (2200 lux) than a 100w bulb (105 lux). Suitable for longer tube lengths.

Flexible Tube System


Provides up to 14 times more light (1500 lux) than a 100w bulb (105 lux). Suitable for shorter tube length and is easier to install.
Em-Tube sizes
